In my opinion typefaces like Warnock, Swift, Scala, Charter, TheSerif could be put in the same category to distinguish them from more traditional serif typefaces. They share similar features with slab-serifs (low contrast strokes and almost blocky serifs) but in use they share more common ground with other serifs. I feel like they’re too unconventional to fit in the same class as old style and traditional humanist serifs. Maybe I’m just looking for a good classifying name (not ‹modern› or ‹contemporary› serif) to lump them together. Just some thoughts from someone who’s sorting out their font library and likes to put suitable labels on things (music that doesn’t fit into a genre/subgenre also irks me when I’m sorting playlists).
